Having complaining about the poor performance in the past, thought I'd give one more try; completely purged any vestiges of EN from my PC. Then installed 10.29.7. This went pretty smoothly and within a few minutes had notebooks visible. After waiting a reasonable time for syncing tried it out. It still took several seconds to bring a note to a window. But the real problem is that editing was unacceptable, any key stroke took one or more seconds to respond on screen. (The PC is high end Dell with plenty of mem etc, W10, everything else runs nice and fast) (editing a note on the web version (Chrome browser) si faster but still has a noticeable keystroke lag)
Purged EN again from PC and installed legacy which comes in as 6.25.3.9348 (I'm running 6.25.1.9091 on my laptop which says it's up to date). Took a while to install and sync but performance is now snappy as ever. And I'm glad to have back again the key short-cut to send a selection to a new note.
